Sikafloor 125 Latex Self Levelling Floor Compound extended information
Consumption: 5 m2 at 3 mm depth
FAQs
How long does it take Sikafloor 125 to dry?
Foot Traffic: The surface can typically accept foot traffic after 2–4 hours at +20°C.
Applying Floor Coverings: Final floor coverings can generally be installed after 8 hours
These times are approximate and can be influenced by factors such as layer thickness, ambient temperature, and relative humidity.
How much does one bag of Sikafloor 125 cover?
Approximately one bag covers 5 metres squared at depth of 3mm.
Please note that coverage can vary based on the condition and porosity of the substrate, as well as application techniques. It’s advisable to consult the product’s technical data sheet and perform a test application to determine exact coverage for your specific project.

Sikafloor 125 Latex Self Levelling Floor Compound APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
Normal Absorbent Concrete/Screed
These substrates do not normally require priming. Damp down floor with clean water without leaving puddles and allow to surface dry. If water is absorbed immediately into substrate, treat as porous surface.
Porous Concrete/Screed
- Seal surface with SikaBond® PVA+ (1 part PVA to 4 parts clean water) ensuring surface is well coated, then allow to dry.
- For highly porous substrates it may be necessary to apply more than one coat to prevent pinholes and cracking/debonding of Sikafloor®-125 Level Latex.
Non Porous/Dense Substrates (quarry/ceramic tiles, terrazzo and smooth concrete etc)
- Mechanically roughen surfaces by grinding or scarifying to provide a mechanical key.
- Alternatively, apply a bonding coat of undiluted Sika- Bond® PVA+ and allow to become tacky before applying levelling compound.
MIXING
Mix thoroughly for a minimum of 3 minutes with an electric stirrer (< 500 rpm).
Unfilled (up to 6 mm thick)
Mix Sikafloor® 125 Level Latex with clean water only. Slowly add 5 parts powder to 1 part water (25 kg powder will require 5 L / 5 kg of water).
Mix in a suitable clean container using a mechanical mixer with a spiral mixing paddle at slow speed until fully mixed and a smooth consistency achieved. Occasionally during hot weather the product may require remixing during the 15 – 20 minute pot life to re- activate the self-levelling characteristics.
DO NOT add extra water. Discard any unused material after 20 minutes from initial mixing.
Filled (up to 25 mm thick)
Mix Sikafloor® 125 Level Latex at a 1:1 ratio with sharp sand then with clean water only.
Slowly add 10 parts powder to 1 part water (25 kg powder plus 25 kg sharp sand will require 5 L / 5 kg of water).
Mix in a suitable clean container using a mechanical mixer with a spiral mixing paddle at slow speed until fully mixed and a smooth consistency achieved. Occasionally during hot weather the product may require remixing during the 15 – 20 minute pot life to re-activate the self-levelling characteristics.
DO NOT add extra water. Discard any unused material after 20 minutes from initial mixing.
SIKAFLOOR 125 – APPLICATION
- Sikafloor® 125 Level Latex can be applied from a maximum thickness of 6 mm (25 mm when filled) down to a featheredge.
- Pour the mixed product onto the floor and spread evenly with a steel trowel to form a thin, tight scrape coat within working time.
- Immediately add further quantities of mixed product to give the desired thickness.
- Trowel marks should flow out of the product to leave a smooth finish (if not, trowel again when the surface is still damp but firm to the touch).
- If required use a spiked roller, within working time, in unfilled product to provide a more uniform surface appearance.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
LIMITATIONS
- Sikafloor® 125 Level Latex is not designed as a final wearing surface and must be covered with a floor covering.
- Not to be used on flexible or unstable substrates.
- Do not use over timber, vinyl coverings, insulation/building boards, anhydrite screeds etc.
- For substrate advice contact Sika Technical Department.
- Do not use on floors with rising damp.
- Do not use as a DPM.
- Porous substrates must be sealed to prevent pinholing and cracking.
- Never exceed water quantity stated.
- Do not add any other materials to the mix.
- Do not use externally.
- Do not use for embedding underfloor heating systems.
- Do not use directly over the top of underfloor heating system pipes or cables.
